Now its Hot Edge by jdoda and combine with Auto Activities by Acedron. I now have three extensions running, one should be enough?! O.T.: the chance that several extensions interfere is proportional to their number...

These extensions are extremely small and don't interfere with TaskBar. Just use them as they are. I'm not gonna integrate them. If someone else wants to do it (with settings for enabling/disabling) and create a pull request I'm gonna merge it.
